It is often difficult to precisely define yielding due to the wide variety of stress–strain curves exhibited by real materials. In addition, there are several possible ways to define yielding: True elastic limit The lowest stress at which dislocations move. This definition is rarely used since dislocations move at very low stresses, and detecting such movement is very difficult. Proportionality limit Up to this amount of stress, stress is proportional to strain (Hooke's law), s… WebJul 31, 2024 · Proof Strength, σ(proof)– The stress at a certain strain offset from the yield strength.
